Regional Administers are no longer enrolling new clients in Single-Family Energy Efficiency & Solar PV services. This LIWP program component is scheduled to sunset in March 2019.

The Low-Income Weatherization Program's (LIWP) Single-Family Energy Efficiency & Solar Photovoltaics (PV) Regional Administrator Component is a regionally administered program that installs no-cost energy efficiency measures, solar water heating, and solar PV in low-income single-family dwellings. These projects reduce residential energy demand and GHG and air pollutant emissions associated with conventional energy generation. The low-income residents that participate in this program benefit from lower energy costs.
